Scores of Twitter users around the world thanked the social networking site, Twitter, today for its decision to postpone a scheduled maintenance which would take the service down for 90 minutes tonight at around 9:45 pm PST. Twitter has become a lifeline for Iranian demonstrators as the microblogging service is providing a vital means of communication amongst protesters as well as the outside world. In response to a large number of users on Twitter pleading the company to reconsider the timing of its scheduled maintenance — given the sensitive timing in the Iran — Twitter decided to reschedule the maintenance to a later time. The following is part of an official post from Twitter:

"A critical network upgrade must be performed to ensure continued operation of Twitter. In coordination with Twitter, our network host had planned this upgrade for tonight. However, our network partners at NTT America recognize the role Twitter is currently playing as an important communication tool in Iran. Tonight's planned maintenance has been rescheduled to tomorrow between 2-3p PST (1:30a in Iran)."
